When the temperature of the input reservoir in a heat engine doesn't change and as the temperature of the emitted gas is lowered, the efficiency of the engine increases.

The detailed step-by-step explanation for the same is as follows:
1. A heat engine operates between two reservoirs: a high-temperature input reservoir (also known as the hot reservoir) and a low-temperature output reservoir (also known as the cold reservoir)
2. The heat engine extracts heat from the input reservoir and converts some of this energy into mechanical work, while the remaining energy is expelled as heat to the output reservoir
3. The efficiency of a heat engine is defined as the ratio of the useful work done by the engine to the heat energy absorbed from the input reservoir
4. According to the second law of thermodynamics, the efficiency of a heat engine is dependent on the temperature difference between the input and output reservoirs
5. When the temperature of the input reservoir remains constant and the temperature of the emitted gas (output reservoir) is lowered, the temperature difference between the two reservoirs increases
6. As the temperature difference between the reservoirs increases, the efficiency of the heat engine also increases, since it is able to convert a greater proportion of the input heat energy into useful work.
In conclusion, when the temperature of the input reservoir in a heat engine doesn't change and the temperature of the emitted gas is lowered, the efficiency of the engine increases due to the increased temperature difference between the reservoirs.

Answer:

True.

Explanation:

The compressibility of a fluid can be defined as a measure of the change in volume (density) with respect to the amount of pressure applied to the fluid. Thus, as the pressure of a compressible fluid increases, both its viscosity and density increases.

Some examples of compressible fluids are vapors, gases, air etc.

Additionally, the compressibility of fluids plays a significant role in the field of science such as in aerodynamics, fluid mechanics, thermodynamics etc.

Viscosity can be defined as a quantity expressing the magnitude of internal friction that restricts the ease of flow between parallel layers at some distance apart having unit speed relative to each other.

These properties of fluids, including viscosity and compressibility are usually being studied by engineers such as civil engineers, in order to test the efficiency of systems under given conditions.

Using the modulus of elasticity, the approximate elongation of the steel alloy specimen when a load of 61,141 N is applied is approximately 0.51788 mm.

To determine the approximate elongation of the steel alloy specimen, we need to know the modulus of elasticity (E) for the material.

Assuming the steel alloy follows Hooke's law and has a constant modulus of elasticity throughout the given load range, we can use the equation:

ε = σ / E

where:

ε = Strain (elongation as a fraction of the original length)

σ = Stress (force applied per unit area)

E = Modulus of elasticity

Given:

Diameter of the specimen = 8.3 mm

Radius (r) of the specimen = 8.3 mm / 2 = 4.15 mm = 0.00415 m

Length of the specimen = 91 mm = 0.091 m

Load applied (P) = 61,141 N

We need the modulus of elasticity (E) for the specific steel alloy. The modulus of elasticity varies for different steel alloys and can typically range from 190 to 210 GPa (Gigapascals).

Let's assume a modulus of elasticity of E = 200 GPa = 200 × 10⁹ Pa.

To calculate the stress (σ), we need the cross-sectional area (A) of the specimen:

A = π * r²

A = π * (0.00415 m)²

A ≈ 5.3809 × 10⁻⁵ m²

Now we can calculate the stress (σ):

σ = P / A

σ = 61,141 N / 5.3809 × 10⁻⁵ m²

σ ≈ 1.136 × 10⁹ Pa

Now we can calculate the strain (ε):

ε = σ / E

ε ≈ (1.136 × 10⁹ Pa) / (200 × 10⁹ Pa)

ε ≈ 0.00568

Finally, we can determine the approximate elongation:

Elongation = ε * L

Elongation ≈ 0.00568 * 0.091 m

Elongation ≈ 0.00051788 m ≈ 0.51788 mm

Therefore, the approximate elongation of the steel alloy specimen when a load of 61,141 N is applied is approximately 0.51788 mm.

Where C1 is the value of the capacitor in arm AB (47 microfarads) and C2 is the value of the capacitor in arm BC (330 microfarads).

Therefore, Cseries = 330 microfarads.

Also, the total resistance of arms CD is the sum of the resistance of the resistor (R) and the reciprocal of the capacitive reactance of the capacitor (1/Xc).

Answer:

the estimated time of submersion is 17.7 years

Explanation:

Given the data in the question;

estimate the time of submersion in years.

we write down the relation between time of submersion and corrosion penetration as follows;

CPR(mpy) = K × W(mg) / [ A(in²) × p(g/cm³) × t(hr) ]

we solve for t

t = (K × W) / ( AP × CPR )

given that;  

Area A = 5 in²

W = 2.3 kg = 2.3 × 10⁶ mg

density of steel p = 7.9 g/cm³

CPR = 200

we know that K is 534

so we substitute

t = (534 × 2.3 × 10⁶ mg) / ( 5 in² × 7.9 g/cm³ × 200 mpy )

t = 1,228,200,000 / 7900

t = 155468.3544 hr

t = 155468.3544 hr × ( 1 yrs / ( 365 × 24 hrs )

t = 17.7 years

Therefore, the  estimated time of submersion is 17.7 years

For a pin-ended column with a hollow circular cross-section, a narrow longitudinal slit, and free ends to warp, the values of axial load that would cause the column to buckle in pure bending mode and pure torsion mode can be determined.  

a) Pure Bending Mode:

To determine the axial load that would cause the column to buckle in pure bending mode, we can use Euler's buckling formula for columns. The critical buckling load for a pin-ended column in pure bending mode is given by:

P_critical = (π² * E * I) / L²

Where:

E = Young's modulus of the material

I = moment of inertia of the cross-section

L = length of the column

The moment of inertia of a hollow circular cross-section can be calculated as:

I = (π / 64) * (D_outer⁴ - D_inner⁴)

Given the dimensions of the column, we can substitute the values and calculate P_critical.

b) Pure Torsion Mode:

To determine the axial load that would cause the column to buckle in pure torsion mode, we can use the torsional buckling formula. The critical buckling load for a pin-ended column in pure torsion mode is given by:

P_critical = (π² * G * J) / L²

Where:

G = shear modulus of the material

J = torsional constant of the cross-section

For a hollow circular cross-section, the torsional constant can be calculated as:

J = (π / 32) * (D_outer⁴ - D_inner⁴)

Substituting the given dimensions and material properties, we can calculate P_critical for pure torsion mode.

By determining the values of P_critical in both pure bending and pure torsion modes, we can understand the axial loads that would cause the column to buckle in each case.

Answer:

115 Ib/ft^3

Explanation:

To determine the maximum dry density in Ib/ft3 we have to calculate :

Bulk unit weight ( yb ) ; W / v

Dry unit weight ( yd. ) :  yb / ( 1 + w )

For every set of data given

assuming  v = 1/30 ft^3

calculating for the 3 data set ( maximum dry density )

weight of soil (W) = 4.40

moisture content (%) (w) = 15.0 = 0.15

Bulk unit weight (yb) = 4.40 / (1/30)  = 132 Ib/ft^3

Dry unit weight ( yd. ) = 132 / ( 1 + 0.15 ) = 114.702 Ib/ft^3

therefore after calculations the maximum dry density in Ib/ft^3 ≈ 115 Ib/ft^3

Answer:

100 kWh

Explanation:

Since the freezer has a rating of 500 watts and runs for 200 hours in a month, the energy consumption can be gotten by getting the product of the rating of the freezer in kilowatts and the amount of time the fridge is on per month.

The rating of the freezer = 500 watts = 0.5 kW, time = 200 h

Energy consumption = rating * time = 0.5 kW * 200 h

Energy consumption = 100 kWh

Therefore the refrigerator uses 100 kWh per month

Numerals

It may seem a bit basic, but a few exercises with the shapes of numbers come before dimensioning. The reason for such a review is simply that incorrectly or carelessly made numbers on a drawing or sketch can easily be misinterpreted by someone on the job. That can be costly.

Therefore, the study of numbers forms is justified.

Explanation:

It is best to organize dimensions for easy reading. The drawing should have constant distances between dimension lines. If clarity cannot be achieved, avoid dimensioning inside objects or having the dimension line touch them.

There are two categories of dimensions: size dimensions and location dimensions.

The measures for the size of features and objects are provided by size dimensions. To locate features and objects, location dimensions are utilized. Drawings may also contain notes.

A measurement is referred to as a Size Dimension if it represents an object's size. A measurement is referred to as a Location Dimension if it represents an object's location.
